What happens when you change the rim size and offset?

[voodoo_ca]

I wanted to first thank everyone here for all the information that I have gleamed from the site over the last while - There are many questions about this topic, and I have been reading them.

This involves changing the Sport 22"s to something for the winter.

Here is what I have gathered so far:

 

Should be able to go down to a 17" rim as the smallest that will still fit around the calipers.

245/70/17 seems to match the sizing of the stock 22"s so I don't have to worry about speed changes.

 

I have found someone with a set of these Sacchi S62 262 rims for sale that he said were on his 2007 Ford Explorer.

 

Now I am trying to determine if everything else will work.

 

First I tried looking up the tire sizes online and thought I found that both were 5x114.3

The only problem was I couldn't find anything on 2013 Edge Sport, only a few years older - but I thought it might be the same.

 

I just did the Canadian Tire fitment wizard online - it did say that can use 22, 20, 18 or 17 rims.

When it gave me back the choices, the above rim was included - but they gave 17x7 5x100 bolt pattern.

 

Either that's the same OR something is wrong - is the 2013 edge sport 5x100 or 5x114.3?

It says Bolt Pattern 1 5x100 bolt pattern 2 5x114.3 - do they have spacing on the same rim to make both of those work, or 2 different rims?

 

I also did an online offset calculator to see what difference that would make on the rim.

Form what I gather the 22"s are 9.5" deep and have a 35mm offset while the new ones are 7" deep and have a 40mm offset.

If I understand correct, the rim moves 31mm away from the inside of the vehicle - giving more clearance - and 33mm away from the outside of the vehicle.

 

Does this difference cause any problems? - it looks to me like it should be ok.

 

Thanks for the support everyone!

As far as I know, the Edge uses 5X114.3 bolt pattern on all models. The only difference is the hub bore size between the 2011 and newer versus the 2010 and older models. The 2011 and newer use a smaller diameter which will not fit the 2010 and older, unless you machine the hub to a larger size. A larger hub size can be used IF you can find the proper hub centric rings sold aftermarket.

 

Make sure whatever wheels you purchase have the correct hub bore size for your model. The 2010 and older uses a size of 70.5mm and the 2011 and newer use 63.4mm.

 

I know owner's here have regularly installed the 22" sport rims onto their non Sport models, replacing the factory wheels with no problems regarding offset. You going the opposite way and installing smaller rims should have no problems as long as you stay within the factory spec range of 40 or so offset.

 

How much you can deviate from that, I really don't know.

Thanks Is973800,

 

I will have to check that hub bore size.

What if the hub bore size is bigger than the one on the car?

It looks to me that it will be 67mm on the rims while the car is 63.4mm - my instinct says that will sit over the hub.

The explorer that these came off of was 70.5mm.

 

comments?

That is what the hub centric rings are for that I mentioned IF you can find them in the correct size. They are usually made of a hard plastic or sometimes metal. They fit over your smaller hub bore and the outside diameter of them allow the larger hub size of the new wheel to be used.

 

Here is a link to give you an idea of how they work.
